Global redshift evolution of f_esc, Lyα with an integration limit on both LFs of 0.04L*. Our results, using the LFs from Thai et al. (2023) are shown in cyan for the modified Schechter function and pink for the general Schechter function. The dotted horizontal line denotes f_esc = 100%. The dash-dotted green curve is from Hayes et al. (2011) in the redshift range of 2.2 − 6.6 and calculated with the integration limit 0.04L*. The red dash-dotted curve is the best fit to all the data shown and the blue dash-dotted curve fits just the data of Thai et al. (2023) (cyan points: modified Schechter function).
